Title: Light subcarrier phase modulator and optical spectrum spread transmitter using same
Inventor: FUKUSHIMA SEIJI
IPC: H04B10/508
Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To obtain the light subcarrier phase modulator which can impose light subcarrier phase modulation, eliminates the need for a complicated electric circuit for up conversion, and can be driven at low cost with low electric power by controlling the delay of light pulses through path switching operation by using an optical component such as an acoustooptic modulator. SOLUTION: A data signal has it high-frequency signal modulated by a modulator and is inputted to the acoustooptic modulator 11. When an light subcarrier superposed on a light carrier is inputted to the acoustooptic modulator 11 through a fiber collimator 12a, it is outputted to one of two fiber collimators 12b and 12c through switch operation corresponding to '1' or '0' of a data signal. A delay line 13 is connected to the fiber collimator 12b and light pulses are delayed by the delay quantity of the delay line 13. The light pulses and light pulses outputted by the fiber collimator 12c are multiplexed by an optical coupler 14, so that the light subcarrier becomes a phase-modulated signal.

Title: Automatic frequency control circuit
Inventor: KOMATSU MICHIHIRO
IPC: H03L7/06
Filed: 1987-03-18
Abstract: PURPOSE:To always ensure a satisfactory locking action with no unstability even though a received signal has deep modulation, by controlling the oscillation frequency of a local oscillating circuit so as to obtain a phase difference '0' between a division signal of a wave detecting oscillation signal and a prescribed reference signal. CONSTITUTION:A phase comparator 33 compares a 2nd intermediate frequency signal with the output signal of an oscillator 32 and produces a signal corresponding to the phase difference between both signals to supply it to the oscillator 32. Thus the oscillator 32 oscillates with the frequency equal to that of the 2nd intermediate frequency signal. A prescaler 20 divides the output signal of the oscillator 32 and supplies them to a PLL circuit 21. The output signal of the oscillator 32 supplied to the prescaler 20 is synchronous with the 2nd intermediate frequency signal and not modulated. As a result, the circuit 21 has always its stable working with no malfunction of the prescaler 20 even in case a received signal has deep modulation.

Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To provide a hierarchical coding/decoding method where a coding quantity and a transmission rate can be controlled and deterioration in a coding efficiency by hierarchical coding can be suppressed. SOLUTION: First a basic layer is coded, and in the case of coding an additional layer next, an existing area of a true value at a higher layer of an object layer is divided. When an object signal in all higher layers is not a significant coefficient, the existing area of the true value in the higher layer just before is divided into three, when the object signal is the significant coefficient, the existing area of the true value in the higher layer just before is divided into two so as to detect the existing area of the true value thereby coding the area information. Since the quantization width in the basic layer is optional, the code quantity and the transmission rate can be controlled and the information of the higher layer is used to encode the additional layer so as to suppress deterioration in the coding efficiency.  In the case of decoding, first the basic layer is decoded, when the object signal of all higher layers of the object layer is not significant coefficient in the case of decoding additional layers, the existing area of the true value in the higher layer just before is divided into three, when the object signal is the significant coefficient, the existing area of the true value in the higher layer just before is divided into two, the area information of the true value is decoded to calculate a quantization representative value.

Abstract: PURPOSE:To obtain a sufficient delay time during a period from the start of energization of a compressor after a power interruption is recovered to the start of energization of a fan motor by using a delay timer circuit comprising a plurality of timers, and turning on the motor when the last timer finishes counting. CONSTITUTION:A delay timer circuit 19 comprises two timers 20, 21 out of which the timer 20 starts to count first. When the timer 21 finishes counting, a fan motor 9 is energized. Thus, one of the timers 20, 21 is stopped during operating due to power interruption, and after the interruption is recovered, the timer 20 starts to count first, and then the timer 21 starts. In this case, the stopped timer is restarted from the stopping time point. Accordingly, the counting time of the timer 19 after the interruption is recovered is the time obtained by subtracting the time of the one timer from the sum of the two timers 20, 21 even in the case of shortest time, and sufficient delay time can be obtained irrespective of timing of the interruption.
